Improvement in inkstands



` 'f UNITED STATES PATENTOFFICE- THOMAS S. HUDSON, OF EAST CAMBRIDGE,MASSACHUSETTS.

||v| PRovEM ENT IN INKSTANDS.

` u Speciicationforming part of Letters Patent No. 35,449, dated J une3, 1862.

To aZZ whom it may concern:

Be it known that I, THoMAs S. HUDSON, a citizen of the United States,and a resident of East Cambridge, in thecounty of Middlesex and State ofMassachusetts, have invented a new and useful or Improved Inkstand forthe use of travelers or others; and I do hereby declare the same to befully described in the following specification, and represented in theaccompanying drawings, of which- Figure 1 is a top view, Fig. 2 anelevation,

` Vand Fig. 3 a vertical section, of it. Fig. 4 is a top view of itscap, Fig. 5 a top view of the cover of such cap, while Fig. 6 is asection of the confining-annulus.

The nature of my invention consists in an inkstand as constructed with aseparate annulus, combined with a perforated vcap and cover in suchmanner as not only to enable the cover to be revolved within the annulusand on the cap, but -be forced down upon the cap by such annulus whenscrewed or moved downward relatively to the cap.

The body or ink-reservoir of the inkstand is shown atA in the drawings,it being provided with a neck, a, on which a perforated cap, b, isplaced and cemented. This cap at its base is to be constructed with amale screw, c c, on which a milled ring or annulus, d, is to be screwed,the said annulus being made with a collar or flange, e, whichv is tooverlap a ange, f, extending from the lower part of a perforated cover,g, which is placed on and extends around the cap b, as shown i'n thedrawings. l A washer, h, of leather or some other suitable material, isplaced within thecover g. Ten passages or holes, z' k, are made-eccentrically through the iuk-reservoirA. By rotating the cover g farenough the holei may be moved entirely away from'the hole k and thelatter be covered. A" small annular lip, Z, is raised around the openingk and on the cap b, in order that the washer h, when pressed downward onsuch lip, may make a tight joint with it.

By partially unscrewing the annulus d I shall be able to freely revolvethe cover g on the cap b; but when the annulus is screwed downward itwill be caused to force the cover g toward the cap b in such manner asto press the washer closely on the lip Z.

I am aware that an inkstand has been made in most, if not all, respectssubstantially like mine, as above described, except that it had noscrew-annulus separate from the cover, the latter being constructed soas to screw directly on the cap. In this inkstand, which has been thesubject of a patent granted to Augustus P.

Grifting, the washer is liable, in consequence of the peculiar action ofthe screws and cover, to become often cut, worn, or crimpled more orless, or turned about within the cap in a manner to cause the hole ofthe washer not to properly correspond with that of the cap. It is verydesirable that the washer should retain its thickness and position,otherwise leakage of ink out of the inkstand will be likely to ensuewhenever it may be turned bottom upward, or other diiiiculties willresult.

In my improved inkstand the cover is entirely independent of the devicesby which it may be fastened down upon the cap, and can be revolvedwithin the screw-annulus, while the latter may be stationary. After thehole -rmly upon the cap by simply screwing down the annulus.

In my improved inkstand there is little or no liability of either wearor displacement of the washer. l

Instead of applying the annulus d to the cap b by screws, as explained,what is termed a bayonet-connection77 lmay be substituted for suchscrews, provided the said bayonet-connection be so made that while theannulus may be revolved in one direction it shall be forced downward, soas to press the cover down upon the cap.

I claim as my invention- An inkstand as constructed with the separateannulus d, combined with the perforated cap b and cover g in manner andso to operate therewith, substantially as described;

THOS. S. HUDSON.
